49ers roster bubble watch: Offensive line
Lock: Aaron Banks, Jake Brendel, Spencer Burford, Jon Feliciano, Colton McKivitz, Trent Williams
Strong bubble: Jaylon Moore, Jason Poe, Matt Pryor, Nick Zakelj
Weak bubble: Leroy Watson
Long shot: Joey Fisher*, Alfredo Gutierrez, Keith Ismael, Corey Luciano*, Ilm Manning*
The Niners didn't use a draft pick on a rookie offensive lineman, but they did grab a few via undrafted free agency. Joey Fisher, however, couldn't finish a practice during rookie minicamp, which doesn't bode well for his roster chances.
But they were slim anyway.
He and the other UDFAs are going to have to overcome a number of free-agent veterans brought in during the offseason, such as Matt Pryor and Jon Feliciano. Of those two, Feliciano carries a contract worth $2.25 million guaranteed, whereas Pryor has zero.
Feliciano isn't going anywhere and likely occupies a role previously held by now-Tennessee Titans lineman Daniel Brunskill.
About the only major question facing San Francisco's O-line aside from depth is who plays at right tackle with Mike McGlinchey now a member of the Denver Broncos.
It appears as if Colton McKivitz is the favorite, for now.
